Fig. 4.5 It is a very common
pattern for the SFL to be pulled
down the front while the SBL
hikes up the back (vertical
lines). This creates a disparity
between the corresponding
structures in the front and the
back of the body (horizontal
lines). This is the foundation for
a host of future problems for
the neck, the arms, breathing,
or the lower back.
Fig. 4.8 The initial track of the
SFL consists of seven tendons
running under the even more
superficial retinacula to combine
into the anterior compartment
of the leg.

forward movement (flexion) or to restrict backward
movement (extension). Trouble abounds when the SFL
myofascia start to pull inferiorly on the skeleton from a
lower stable station, rather than pulling superiorly from
an upper stable station, i.e. the belly muscles start acting
to pull the ribs toward the pubic bone, instead of bring-
ing the pubic bone up toward the ribs.
Common postural compensation patterns associated
with the SFL include: ankle plantarflexion limitation,
knee hyperextension, anterior pelvic tilt, anterior pelvic
shift, anterior rib and breathing restriction, forward
Fig. 4.7 The reciprocal relationship between the SBL and SFL can
be seen in these two poses. In (A), the SBL is contracted and the
SFL stretched, vice versa in (B).
